Rupture processes of the main shock of the 2016 Kumamoto earthquake was estimated based on waveform inversion analyses using empirical Green's functions. The main asperity was located approximately 15 km northeast of the hypocenter. In the region between the hypocenter and Mashiki, both slip and slip velocity were rather small. Therefore, it is not appropriate to conclude that the damaging ground motions in Mashiki were caused by forward directivity effects. In the analyses, near-source strong ground motions were used. Possible effects of soil nonlinearity on the inversion results are discussed.
